hi, i have read everything i can find, but still can't seem to get my puppy to boot using a grub2 menu built from ubuntu.
currently i have added 4 slightly different boot options for puppy, but none of them work. i update the 40* file and run update-grub.
the error i get is:
error: unknown filesystem or error: file not found (this one probably is a result of entering the incorrect disk partition #)
you need to load the kernel first
press any key to continue

i get one of the two errors above on all 4 options i have entered.
first time i tried this using the puppy load to hard drive option.
i then reformatted the partition, and reloaded puppy with a frugal install.

after the install to hd thru puppy, i boot ubuntu and run update-grub
i have modified the 40* line with various options, but none work.

i have not tried to install grub thru puppy, since i was using ubuntu to update grub. do i need to install grub via puppy, then overlay it with ubuntu?
thanks for your help.
looks like i need to move this to a different folder, but not sure how to do that.. sorry for the problem.

where "puppy" is the subdir of frugal install and z is 0 if x is a, z is 1 if x is b and so on,. If your drive is a external usb hd change pmedia=atahd with pmedia=usbhd and so on. Save 40_custom. Then boot ubuntu and in terminal:

That does not work. Ubuntu has to be first it is set up that way.
Then you add puppy on the 40 things and it is very important
to get that one right or else it does not each show puppy as a choice even.

So use the link I have in my signature and use proper keywords
for searching through this forum for to find some post that tells
about it.

I trust that the member/user rcrsn51 of this forum may have a post
somewhere
Hope you find a solution and if you do would be much appreciated
if you share it here in the thread too. Could help others_________________I use Google Search on Puppy Forum
not an ideal solution though

So change the number there to the correct partition.
Remember that Grub2 has another way to count
then what grub4dos have. Others can tell you how.
I don't know. But I guess them are different like this

root=(hd0,7) in grub2 becomes
root=(hdo,6) in grub4dos?_________________I use Google Search on Puppy Forum

I thought I replied, but maybe another post came in while i was trying, and somehow i lost my response.. if not, i apologize for submitting this twice..
First, i want to thank all of you for your support !! I really appreciate the help.
Seems like I have already tried most of the suggestions, but maybe i am missing the key element somewhere.. here is the output from df, fdisk, my menu entries, etc that should give the more qualified the details needed to solve this..
first, here are the various entries i added to the 40* entry in Ubuntu..

i will go thru each of your posts and try to figure out what i need to do different.
correct me if i am wrong, but i think i can add multiple variations to the 40* file, and not hurt anything. if one of them happens to be right, then it should boot, and i can then delete the others.. or at least that is what i was thinking..

i was reading some other posts, and saw where someone added a uuid entry, so i tried that..
basically added: search --no-floppy --fs-uuid --set 5ddaba1b-a977-4409-a78d-09f6993275a8 (except the 5dd.. was actually 6..something that is the uuid from that partition).
rebuilt grub.
now i do not get the unknown filesystem or file not found error message.
i just get the "you need to load the kernel first" error message.

probably getting the error msg from my opt b, which uses hd0,6 instead of hd0,5
not really sure what command tells me how a partition is formatted, but the df command shows sda6 as ID 83. i am pretty sure when i formatted it, i selected ext4.
